This has to be some US-patent thingy, since in Europe you cannot enforce a patent on something that is selfmade for own use. That would be pointless anyway, wouldn't it? Whether a SW product or self-made piece of hardware, I really want to see how this is done in the US Is the police going to come to your door (everybody's door? how often? once a month or every friday?) and raid your home for illegal things you might have made in your kitchen/bedroom/garage??? I know it is a police state but how are they going to get enough men to do that across the 52 states...
